Active PFC and Sine Wave Power
Active PFC
High end PCs and workstations include
graphics cards, processors, and other
devices that consume more power than
home computers. Gaming PCs often
have power hungry, high performance
processors and graphics cards. And
many federal, state, and educational
institutions specify that new PCs have
internal switching power supplies with
ENERGY STAR® ratings. To meet all these
demands and improve energy efficiency,
leading manufacturers use switching
power supplies with active power factor
correction (Active PFC).
Sine Wave Power
Electronic devices using power supplies
with Active PFC circuits depend on sine
wave power to run optimally. Sine wave
power is the type of power supplied by
electric utility companies. Equipment with
Active PFC power supplies can be more
susceptible to stress or malfunctioning
when running on a UPS that provides
simulated sine wave output, resulting
in data loss or equipment damage.
Here’s why:
CONTACT
A simulated sine wave output (Fig. 1) has
a power gap at each cycle. When the UPS
switches to battery current, a power supply
with an Active PFC circuit may detect that
power gap and shut itself down.
This power gap may not always cause the
power supply to switch off, but any sudden
failure can have serious consequences.
UPS systems with that deliver true sine
wave output (Fig. 2) prevent unexpected
shutdowns and damaging stress.
Recommendations
PFC Sinewave UPS systems from
CyberPower Systems provide true sine
wave power to protect ENERGY STAR
compliant PCs, workstations, networking
hardware, and servers. To find whether
SIMULATED SINE WAVE
your equipment uses an Active PFC power
supply, check the device itself, review the
user manual, or contact the manufacturer.
For optimal performance, connect any
equipment with Active PFC power supplies
to a UPS system with true sine wave
output. To match a UPS system to your
current and future requirements, visit our

Peak Voltage
Figure 1. A simulated sine wave dwells on peak voltage
within each cycle, and on zero voltage when switching
polarity. Those lag times are too short for human
perception—but potentially long enough for an Active PFC
circuit to sense a problem and shut down unexpectedly.

in the cycle. It has instantaneous zero voltage when
switching polarity, and only momentary peak voltage.
